  h3(id='res.render') res.render(view, [locals], callback)

  p.
    Render a <code>view</code> with a callback responding with
    the rendered string. When an error occurs <code>next(err)</code>
    is invoked internally. When a callback is provided both the possible error
    and rendered string are passed, and no automated response is performed.

  +js.
    res.render('index', function(err, html){
      // ...
    });

    res.render('user', { name: 'Tobi' }, function(err, html){
      // ...
    });
